Edible Sea Urchins: Biology and Ecology


Book Description

Sea urchins are a major component of marine environments found throughout the world's oceans. A major model for research in developmental biology, they are also of major economic importance in many regions and interest in their management and aquaculture has increased greatly in recent years. This book provides a synthesis of biological and ecological characteristics of sea urchins that are of basic scientific interest and also essential for effective fisheries management and aquaculture. General chapters consider characteristics of sea urchins as a whole. In addition, specific chapters are devoted to the ecology of 17 species that are of major commercial interest and ecological importance. Features include: • A synthesis of what is known about the basic biological characteristics of the sea urchin, useful for the direction of future research. • Case histories of 17 species that illustrate their ecological role in a variety of environments. • With the catastrophic decline in fisheries resulting primarily from over-fishing, it is essential that the populations be managed effectively and that aquaculture be developed. This book provides knowledge of the biology and ecology of the commercially important sea urchins that will contribute to these goals. • The only book available in present literature devoted to sea urchins. With this new title experts provide a broad synthetic treatment and in depth analysis of the biology and ecology of sea urchins from around the world, designed to provide an understanding of the group and the basis for fisheries management and aquaculture.

Regional review on status and trends in aquaculture development in sub-Saharan Africa – 2020


Book Description

This review provides an overview of the status, trends, challenges and projections for aquaculture in sub-Saharan Africa (SSA) and evaluates the major trends during previous five years. While the sector still faces various internal and external challenges, the inherent natural potential of the region and rapidly increasing demand for fish has resulted in increased prioritization of aquaculture in almost all SSA countries and the African Union and subsidiary bodies have given special attention to the sector development. In order to realize its full potential, the SSA region needs to address a combination of overarching factors limiting aquaculture development so far, such as ineffective development approaches, weak governance frameworks, underdeveloped value chains and low availability as well as the high cost of key production inputs. Strengthened value chains for tilapia and catfish, promotion of new species, improved biosecurity, continued development of certification and associated harmonized best practices, improved information systems and innovations to address climate-change related impacts are some of the matters to be addressed. Financial institutions and private sector (national and international) have equally started investing, even though in the global picture such interventions may seem negligible, which makes the continent to call for more and higher levels technical and financial assistance from international partners. Upscale the status of production and productivity via healthy investments would help the sector to generate a variety of benefits including food security, livelihoods, employment, domestic and intra-regional markets, foreign currency income and other socio-economic benefits.

The ensuing conclusions and recommendations were crystallized in a 10-point Resolution on Village Aquaculture Development in Africa.




Aquaculture Development In Less Developed Countries


Book Description

Aquaculture may not be the panacea for the world's food problems, but It has the potential to make important contributions to diet and incomes in some areas. This book, intended to improve planning for further development of aquaculture, examines the factors that can determine the success or failure of aquaculture projects in developing countries.




Regional review on status and trends in aquaculture development in Latin America and the Caribbean – 2020


Book Description

This document reviews the development of the aquaculture industry in the Latin America and the Caribbean region over the past decade. In 2018 aquaculture production in the region amounted to an estimated 3.1 million tonnes of aquatic products (excluding seaweeds) worth USD 17.2 billion at first sale. This food sector is vastly concentrated in a few countries with the combined output from Brazil, Chile, Colombia, Ecuador and Mexico representing over 85 percent of the total regional production. Atlantic salmon, rainbow trout, tilapia, whiteleg shrimp and the Chilean mussel collectively contributed 80.4 percent and 85.9 percent of the regional production by volume and value, respectively. Marine aquaculture has been the dominant production environment in the region for the past two decades, accounting for 70.1 percent of the farmed output in 2018. Production models vary widely, with a concentration of large-scale companies in Chile, while primarily small- and/or medium-size operations in Brazil, Peru and several other countries. Introduced species remain top on the list among those farmed such as tilapia and the different salmonids both of which have contributed to local livelihoods and employment. Tilapia farming has contributed significantly to food security in many countries of the region while the largest proportion of farmed salmons have been destined to the export markets. Production prospects remain promising, however the industry requires in general better governance, the adoption at all levels of appropriate technologies and best practices, and renewed efforts to guarantee environmental sustainability and social acceptance as well as competitiveness and foresight to deal with climate and market changes. The small island developing states (SIDS) face additional challenges including limited expertise, high production costs, poor seed supplies, as well as extreme and destructive weather events. The report discusses issues that require wider regional attention for the aquaculture sector to grow. Key recommendations focus on governance-related improvements highlighting the need for solid sectoral development plans, support policies, and effective rules and regulations. The promotion of a stronger cooperation among the countries in the region as well as further afield on technical matters, species diversification and equal support to smalland large-scale farming operation are identified as key elements to foster investment and help the region gain a solid position among world aquatic food producers.
